On Tuesday, 22-year-old Kayla L. Pearson of 1910 N. Lexington Drive, Janesville, pleaded guilty to armed robbery, theft and false imprisonment. Each charge was modified because she was a party to the crime.

Adams and another man, 25-year-old Christopher Kimps of Whitewater, broke into the couple's home, pointed guns at them, beat them and bound them with duct tape during the robbery, according to court documents.

Pearson had dated the couple's son for two years, authorities said, and lived in the town of Fulton home for months. She told the group about the house and its supply of guns, according to court documents.

Along with a fourth accomplice, 20-year-old Sarah A. Buckingham of Monroe, the trio made off with about $2,500 in cash, 35 guns and a pickup truck, court documents show.

Kimps later led police on a chase through downtown Janesville in the truck, authorities said.

The suspects were arrested in Sauk County a few days after the robbery.

Kimps pleaded guilty last week to five felony charges and is set for a sentencing hearing Feb. 4.

Adams' sentencing hearing will be Jan. 24, while Pearson's will be Jan. 30.
